Problems solved by technology

[0002] Anti-explosion containers are widely used in pyrotechnics, public safety emergency and other fields, but at present most anti-explosion containers are connected by bolts and buckles. In this design, the end caps of anti-explosion containers are often It is the weak link of the design. Under the working condition of bearing the impact of explosive load, it is easy to fail due to excessive deformation of the end cover; some anti-explosion containers adopt wedge-slotted structure (generally 4 wedges) to achieve an approximate full-wedge The structural cover plate design can effectively improve the stress state of the cover plate, but the wedge-type full-wedge structure is complex, with a large number of parts and small parts. Under the impact of the explosive load, the connected parts are easy to fly out and form flying pieces. Hazard to surrounding personnel or equipment

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] as attached figure 1 As shown, a full wedge anti-explosion container is mainly composed of a shell 1, a cover plate 2, a wedge 3 and a locking member 4, and the whole structure is only composed of six parts.

[0019] The shell structure of the full wedge anti-explosion vessel is as attached figure 2 As shown, the shell adopts a spherical design as a whole. According to investigation and analysis, under the same load, the spherical shell has smaller principal stress than other forms of shells such as cylindrical shells. The opening adopts an elliptical opening, and the difference between the long and short axes of the ellipse is fully utilized to realize the axial fixation of the cover plate.

[0020] The flange neck at the upper end of the shell is the key to this design, and the wedge bar slot 31 and the cover plate slot 21 are dist...

Abstract

The invention discloses a full-wedge type anti-explosion container. The container comprises a shell body, a cover plate, wedge strips and a locking piece, wherein the shell body uses a spherical design overall, and an opening of the shell body is an oval; a flange neck is arranged on the oval opening, and wedge strip clamping grooves and cover plate clamping grooves are formed in the flange neck;the wedge strip clamping grooves are located on the cover plate clamping groove, the cover plate clamping grooves are in a circle, and the wedge strip clamping grooves are in a long circle shape; thecover plate adopts an oval design, and a swallowtail-shaped guide rail is arranged on the upper surface of the cover plate along the center of a short axis; swallowtail-shaped grooves are formed in the bottom surfaces of the wedge strips, and the swallowtail-shaped guide rail cooperates with the swallowtail-shaped grooves; the wedge strips are two opposite semicircular arc-shaped structures, an inclined plane with a downward gradient is arranged on the edge of the upper surface of each semicircular arc-shaped structure of the corresponding wedge strip, and a positioning hole is formed in one end of each wedge strip; and the wedge strips are assembled on the cover plate and are fixedly connected with the cover plate, so that the wedge strips are prevented from slipping off the cover plate.The full-wedge type anti-explosion container is simple in structure, safe, reliable and rapid in opening and closing.
